Functional Components of a Computer System
A computer system contains many different objects such as a CPU, memory, disks, etc. These must all be connected for the system to function.
The wires used to connect the components are called buses.
The following section shows the connections within a computer system and describes how data is transferred between the components.
The internal components of the CPU are described in the next section.
Remember that the descriptions are concerned with real, physical things such as boards, chips and cables, as you can see here.
